Charles Jules Henri Nicolle

“The time will come when we shall be able to vaccinate against all infectious diseases.”

“There are infectious diseases of which we are ignorant.”

“It is... the nobility of the physician's role to have these blind certainties, to combine them with his knowledge, and to risk his person.”

“Thus, an infectious disease is born, passes, and disappears. Or it is born, passes, and reappears. Or it is born and establishes itself.”

“In truth, we have known for a long time that there is a biological struggle between all living beings.”
